Overview
The Titan HLC-0520E is an integrated high-low temperature circulating bath engineered for precise thermal control in laboratory and analytical applications requiring stable, bidirectional temperature regulation. Utilizing a dual-mode thermoelectric-compressor hybrid architecture—optimized for rapid cooling via refrigerant-based vapor compression and efficient heating via high-wattage resistive elements—the unit maintains setpoint accuracy across its full operational range of −20 °C to +100 °C. Its closed-loop circulation system delivers consistent thermal transfer to external devices such as spectrophotometer cells, reaction jackets, viscometers, or calorimetric sensors. Designed for continuous-duty operation under ambient conditions up to 30 °C and relative humidity ≤70% non-condensing, the HLC-0520E meets core engineering requirements for reproducibility in method-critical workflows, including those aligned with ISO/IEC 17025-accredited laboratories.
Key Features
- Integrated design eliminates need for external chiller or heater units—reducing footprint, interconnection complexity, and potential leak points.
- High-stability temperature control with ±0.05 °C fluctuation over time, verified per ASTM E2877-21 (Standard Guide for Calibration of Liquid-in-Glass Thermometers) using traceable Pt100 reference probes.
- Water-cooled condenser enables sustained cooling performance even during extended operation at low setpoints; compatible with standard laboratory tap water or recirculating cooling towers.
- Programmable dual-pump system: adjustable flow rate up to 22 L/min with selectable pressure/suction configuration (0.3 bar discharge / 0.2 bar suction) for compatibility with high-backpressure applications (e.g., jacketed reactors or inline filtration assemblies).
- 5-liter stainless-steel reservoir with level sensor, corrosion-resistant internal wetted parts (316L SS tubing, EPDM seals), and built-in air purge valve to minimize bubble formation in sensitive optical or electrochemical setups.
- Over-temperature, low-flow, and dry-run protection circuits comply with IEC 61010-1:2012 safety requirements for laboratory equipment.
Sample Compatibility & Compliance
The HLC-0520E supports thermal conditioning of diverse sample interfaces—including glass, quartz, PTFE, and stainless-steel vessels—without introducing thermal lag or gradient distortion. Its fluid path is chemically inert to common solvents (e.g., water, ethylene glycol/water mixtures, silicone oils up to 100 cSt), enabling use in pharmaceutical stability chambers, polymer rheology stations, and materials testing rigs. The unit conforms to CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), RoHS 2011/65/EU, and carries factory calibration documentation traceable to NIM (National Institute of Metrology, China). While not inherently 21 CFR Part 11 compliant, its analog/digital I/O interface allows integration into validated systems when paired with audit-trail-capable SCADA or LIMS platforms.
Software & Data Management
The HLC-0520E includes an embedded microprocessor controller with intuitive membrane keypad and 4.3-inch TFT display showing real-time bath temperature, setpoint, flow rate, and system status codes. Optional RS485 Modbus RTU or USB-to-serial interface enables remote parameter setting, data logging (via host PC), and synchronization with external PID controllers. Logged data includes timestamped temperature readings at user-defined intervals (1–600 seconds), supporting GLP-compliant record retention when exported to CSV or Excel formats. Firmware updates are performed via secure USB drive; no cloud connectivity or proprietary software installation is required.
Applications
- Temperature-controlled UV-Vis and FTIR spectroscopy cell holders
- Calibration of thermocouples, RTDs, and infrared thermometers against fixed-point references
- Thermal cycling of catalyst beds in gas-phase reaction studies
- Viscosity measurement support for rotational rheometers operating under controlled thermal gradients
- Preconditioning of test specimens per ASTM D696 (Coefficient of Linear Thermal Expansion) and ISO 11359 (Dynamic Mechanical Analysis)
- Stabilization of laser diodes and photodetectors in optical metrology setups
FAQ
What is the recommended heat transfer fluid for operation below 0 °C?
A 30% aqueous ethylene glycol solution (freezing point ≈ −15 °C) is recommended; avoid methanol or acetone due to seal degradation and vapor pressure risks.
Can the HLC-0520E be used with open-bath accessories?
No—it is designed exclusively for closed-loop external circulation; open-bath operation voids warranty and compromises temperature uniformity and safety compliance.
Is external water cooling mandatory?
Yes. The water-cooled condenser requires a minimum supply pressure of 1.5 bar and flow rate ≥2 L/min at inlet temperatures ≤25 °C for rated cooling capacity.
Does the unit support ramp-and-soak temperature programming?
Not natively—the controller supports single-setpoint hold only; multi-step profiles require external PLC or PC-based scripting via Modbus.
What maintenance intervals are specified for long-term reliability?
Condenser descaling every 6 months (if using hard tap water), annual inspection of pump impeller wear and seal integrity, and biannual verification of temperature sensor drift using certified reference standards.
